Steinberg UR22and REW: high frequency problem

[quasar]

Hi,

I have a problem using the UR22. The REW software is amazing and I used quite a lot for subwoofer alignment but the transfunktion of the soundcard looks wierd higher than 10kHz for my UR22 soundcard. (I just just connected output to input)

When I use matlab to do a measurement I dont have that problem. (see screenshots)

Is anybody using the same soundcard and can relate ?
Attached are the photos (top:matlab, bottom:REW)

Thanks

I've used UR22 and UR22 MkII and not seen anything like that. Do you have a cal file loaded in REW?
